  • Summary
  • Applications

    HVAC-system pumping and control; general purpose pumping; industrial/ process pumping and control (water or glycol based)

  • Description

    Base mounted end-suction horizontal pumping unit with integrated intelligent controls for easier installation and superior energy performance. Saves up to 75% in energy over comparable traditional constant speed or variable frequency operated pump installations

  • Materials
    • Cast-iron or ductile iron casing
    • Bronze impeller
    • Sintered silicon carbide mechanical seal
  • Configuration

    On-board Intelligent Variable Speed controls with Sensorless control. Split-coupling design and outside balanced. Controls enclosure UL type 12 for indoor applications. Supplied with NEMA premium TEFC motors

  • Performance range

    25 to 3,500 USgpm (1.5 to 220 L/s) flow; 10 to 300 ft (3 to 90 m) head (composite curves available)

  • Temperature

    300oF (150oC)

  • Power Range

    1 hp to 125 hp (0.75 kW to 90 kW)

  • Size

    1.5" to 8” discharge (40 mm to 200 mm)

Lowest installed cost

  • Integrated intelligent controls eliminate separate mounting of variable frequency drive (VFD) as well as procurement, installation (incl. wiring), calibration and upkeep of differential pressure sensor
  • Expertly staggered product line for perfect pump match-up and selection especially in retrofit situations
  • Superior energy performance qualifies for significant cost recovery under utility and government rebate programs
  • Design Envelope selections frequently recommend a no-risk smaller motor and/or pump which reduces installed cost.
